Multiply all combinations of two lists [closed]

Answer 1

You can use for loops:

Operation for each item in A with each item in B:

A=[1,3,5,7,9]
B=[2,4,6,8]

C = [] #Create an empty list
for i in A: #iter each element in A
    for j in B: #iter each element in B
        mult = i * j
        C.append(mult) #Append the result in the list C
print(C)

Operation with a random item in A with each item in B:

import numpy as np

A=[1,3,5,7,9]
B=[2,4,6,8]

C = [] #Create an empty list
for i in A: #iter each element in A
    i = np.random.randint(len(A)) #Chose a random number from A
    for j in B: #iter each element in B
        mult = A[i] * j #Multiply a random number from A with each element in B
        C.append(mult) #Append the result in the list C
print(C)
